Being a slightly improved Excel has significant advantages as well:
It's more accessible to people who are not coders but need to do statistics on real data, i.e. almost all researchers.
Although personally, I would use R/Python (the UI is more suited to me, and it's free, and I trust the results a little more, and I can read the code if I need to)... do you actually need anything more than SAS/SPSS provides? I doubt it.
